Calcilytic compounds

ABSTRACT

Novel arylalkylamino compounds exhibiting calcilytic properties are provided.

This is a 371 of International Application PCT/US98/06928, filed Apr. 8, 1998, which claims benefit from the following Provisional Applications: 60/042,724, Apr. 8, 1997, 60/061,327, Oct. 8, 1997; 60/061,329, Oct. 8, 1997; 60/061,330, Oct. 8, 1997; 60/061,333, Oct. 8, 1997; 60/061,331, Oct. 8, 1997.

The present invention relates to novel arylalkylamine calcilytic compounds, pharmaceutical compositions containing these compounds and their use as calcium receptor antagonists.

In mammals, extracellular Ca²⁺ is under rigid homeostatic control and regulates various processes such as blood clotting, nerve and muscle excitability, and proper bone formation. Extracellular Ca²⁺ inhibits the secretion of parathyroid hormone (“PTH”) from parathyroid cells, inhibits bone resorption by osteoclasts, and stimulates secretion of calcitonin from C-cells. Calcium receptor proteins enable certain specialized cells to respond to changes in extracellular Ca²⁺ concentration.

PTH is the principal endocrine factor regulating Ca²⁺ homeostasis in the blood and extracellular fluids. PTH, by acting on bone and kidney cells, increases the level of Ca²⁺ in the blood. This increase in extracellular Ca²⁺ acts as a negative feedback signal, depressing PTH secretion. The reciprocal relationship between extracellular Ca²⁺ and PTH secretion forms an important mechanism maintaining bodily Ca²⁺ homeostasis.

Extracellular Ca²⁺ acts directly on parathyroid cells to regulate PTH secretion. The existence of a parathyroid cell surface protein which detects changes in extracellular Ca²⁺ has been confirmed. See Brown et al., Nature 366:574, 1993. In parathyroid cells, this protein, the calcium receptor, acts as a receptor for extracellular Ca²⁺, detects changes in the ion concentration of extracellular Ca²⁺, and initiates a functional cellular response, PTH secretion.

Extracellular Ca²⁺ influences various cell functions, reviewed in Nemeth et al., Cell Calcium 11:319, 1990. For example, extracellular Ca²⁺ plays a role in parafollicular (C-cells) and parathyroid cells. See Nemeth, Cell Calcium 11:323, 1990. The role of extracellular Ca²⁺ on bone osteoclasts has also been studied. See Zaidi, Bioscience Reports 10:493, 1990.

Various compounds are known to mimic the effect of extra-cellular Ca²⁺ on a calcium receptor. Calcilytics are compounds able to inhibit calcium receptor activity, thereby causing a decrease in one or more calcium receptor activities evoked by extracellular Ca²⁺. Calcilytics are useful as lead molecules in the discovery, development, design, modification and/or construction of useful calcium modulators which are active at Ca²⁺ receptors. Such calcilytics are useful in the treatment of various disease states characterized by abnormal levels of one or more components, e g., polypeptides such as hormones, enzymes or growth factors, the expression and/or secretion of which is regulated or affected by activity at one or more Ca²⁺ receptors. Target diseases or disorders for calcilytic compounds include diseases involving abnormal bone and mineral homeostasis.

Abnormal calcium homeostasis is characterized by one or more of the following activities: an abnormal increase or decrease in serum calcium; an abnormal increase or decrease in urinary excretion of calcium; an abnormal increase or decrease in bone calcium levels (for example, as assessed by bone mineral density measurements); an abnormal absorption of dietary calcium; an abnormal increase or decrease in the production and/or release of messengers which affect serum calcium levels such as PTH and calcitonin; and an abnormal change in the response elicited by messengers which affect serum calcium levels.

Thus, calcium receptor antagonists offer a unique approach towards the pharmacotherapy of diseases associated with abnormal bone or mineral homeostasis, such as hypoparathyroidism, osteosarcoma, periodontal disease, fracture healing, osteoarthritis, rheumatoid arthritis, Paget's disease, humoral hypercalcemia associated with malignancy and fracture healing, and osteoporosis.

SUMMARY OF THE INVENTION

The present invention comprises arylalkylamine derivatives represented by Formula (I) and their use as calcium receptor antagonists which are useful in the treatment of a variety of diseases associated with abnormal bone or mineral homeostasis, including but not limited to hypoparathyroidism, osteosarcoma, periodontal disease, fracture healing, osteoarthritis, rheumatoid arthritis, Paget's disease, humoral hypercalcemia associated with malignancy and fracture healing, and osteoporosis.

The present compounds maintain calcium receptor activity and selectivity while having minimal affinity for the beta adrenergic receptor.

The present invention further provides a method for antagonizing calcium receptors in an animal, including humans, which comprises administering to an animal in need thereof an effective amount of a compound of Formula (I).

and pharmaceutically acceptable salts thereof.

The present compounds can be formulated as pharmaceutically acceptable salts and complexes thereof. Pharmaceutically acceptable salts are non-toxic salts in the amounts and concentrations at which they are administered.

Pharmaceutically acceptable salts include acid addition salts such as those containing sulfate, hydrochloride, fumarate, maleate, phosphate, sulfamate, acetate, citrate, lactate, tartrate, methanesulfonate, ethanesulfonate, benzenesulfonate, p-toluenesulfonate, cyclohexylsulfamate and quinate. Pharmaceutically acceptable salts can be obtained from acids such as hydrochloric acid, maleic acid, sulfuric acid, phosphoric acid, sulfamic acid, acetic acid, citric acid, lactic acid, tartaric acid, malonic acid. methanesulfonic acid, ethanesulfonic acid, benzenesulfonic acid, p-toluenesulfonic acid, cyclohexylsulfamic acid, fumaric acid, and quinic acid.

Pharmaceutically acceptable salts also include basic addition salts such as those containing benzathine, chloroprocaine, choline, diethanolamine, ethylenediamine, meglumine, procaine, aluminum, calcium, lithium, magnesium, potassium, sodium, ammonium, alkylamine, and zinc, when acidic functional groups, such as carboxylic acid or phenol are present.

The present invention provides compounds of Formula (I) above which can be prepared using standard techniques. An overall strategy for preparing preferred compounds described herein can be carried out as described in this section. Using, the protocols described herein as a model, one of ordinary skill in the art can readily produce other compounds of the present invention.

A general procedure used to synthesize many of the compounds can be carried out as described in Scheme 1, above: A solution of aryl alcohol (X—OH) in acetone was treated with an appropriate base such as K₂CO₃, heated for 15 min. R-glycidyl nosylate was added and the reaction continued overnight to give the corresponding glycidyl ether (Scheme 1). In the case of an alkyl alcohol, a stronger base, e.g. NaH in DMF was used. This method can also be used for aryl alcohols. A solution of the substituted glycidyl ether and excess amine (typically 1,1-dimethyl-2-(4-methyloxyphenyl)ethylamine) in absolute ethanol, acetonitrile, THF or any other similar solvent in the presence of a suitable catalyst such as LiClO₄ is stirred overnight at reflux. The product is purified by normal phase chromatography. Hydrochloride salts are prepared by treatment of the corresponding free base with HCl either in gas phase or 4M dioxane solution, or any other standard method.

The synthesis of the corresponding o-substituted aryl ethers is described in Scheme 2-9. For example, treatment of a 2-cyano-4-nitrophenol (Scheme 2) with K₂CO₃ followed by methyl iodide, yields the corresponding aryl methyl ether, treatment with Fe powder or any other reducing agent capable of reducing the aryl nitro group in the presence on the nitrile, gives the corresponding aniline. Reaction of the thus obtained aniline with an appropriate sulfonyl or carbonyl chloride such as tosyl, or mesyl chloride or 4-morpholinecarbonyl chloride, in the presence or triethyl amine produces the corresponding sulfonamide or urea. Alkylation of the sulfonamide nitrogen can be carried out via deprotonation with an appropriate base such as NaH in an appropriate anhydrous solvent such as DMF, followed by treatment with the desired alkyl halide such as benzyl bromide. The methyl ether was then removed with Me₃PhSi and I₂ or with LiI in collidine, or any other standard deprotection method known to a chemist skilled in the art. The 2,3-disubstituted methyl ether (Scheme 3) is treated with bromine in the presence of Fe resulting in regiospecific bromination. The resulting bromide can then be treated under carbonylamidation conditions, (Ph₃)₄Pd, CO, R₁R₂NH, DMF, heat to give the resulting amide which is deprotected with LiI in collidine to give the corresponding aryl alcohol. Treatment of an ortho-substituted aryl ether Scheme 4 with SOCl₂ followed by a primary. or secondary amine gives the p-sulfonamide. The methyl ether is then removed with Me₃PhSi and I₂ or with LiI in an appropriate solvent such as collidine, or any other deprotection method known to a chemist skilled in the art (Scheme 2), to yield the desired arylalcohol. The methyl aryl ether (Scheme 5) is converted to the corresponding aryl alcohol with AlCl₃/EtSH. The cyano group is introduced selectively adjacent to the aryl alcohol by treating the aryl alcohol with paraformaldehyde and SnCl₄ to give the formyl derivative. Conversion of the formyl group to the corresponding oxime and dehydration with Ac₂O gives the cyano-aryl ester. Final hydrolysis of the aryl ester gives the desired aryl alcohol. Deprotection of the methyl aryl ether of the ketone(Scheme 6). gives the aryl alcohol as well as the thio enolether. Nucleophilic displacement of the aryl fluoride (Scheme 7) with the potassium salt of the phenol gives a biaryl ether which is reduced and then cyclized to give a cyclic amide which is converted to the corresponding aryl alcohol via deprotection with AlCl₃/EtSH. The amide from Scheme 7 is reduced to the tricyclic anilide (Scheme 8) which is converted to the corresponding aryl alcohol via deprotection with AlCl₃/EtSH. The tricyclic anilide from Scheme 8 is alkylated with the appropriate electrophile to give the corresponding N-alkylated material (Scheme 9).

With appropriate manipulation and protection of any chemical functionality, synthesis of the remaining compounds of Formula (I) is accomplished by methods analogous to Schemes 1-9.

In order to use a compound of Formula (I) or a pharmaceutically acceptable salt thereof for the treatment of humans and other mammals, it is normally formulated in accordance with standard pharmaceutical practice as a pharmaceutical composition.

The calcilytic compounds can be administered by different routes including intravenous, intraperitoneal, subcutaneous, intramuscular, oral, topical (transdermal), or transmucosal administration. For systemic administration, oral administration is preferred. For oral administration, for example, the compounds can be formulated into conventional oral dosage forms such as capsules, tablets, and liquid preparations such as syrups, elixirs, and concentrated drops.

Alternatively, injection (parenteral administration) may be used, e.g., intramuscular, intravenous, intraperitoneal, and subcutaneous. For injection, the compounds of the invention are formulated in liquid solutions, preferably, in physiologically compatible buffers or solutions, such as saline solution, Hank's solution, or Ringer's solution. In addition, the compounds may be formulated in solid form and redissolved or suspended immediately prior to use. Lyophilized forms can also be produced.

Systemic administration can also be by transmucosal or transdermal means. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, bile salts and fusidic acid derivatives. In addition, detergents may be used to facilitate permeation. Transmucosal administration, for example, may be through nasal sprays, rectal suppositories, or vaginal suppositories.

For topical administration, the compounds of the invention can be formulated into ointments, salves, gels, or creams, as is generally known in the art.

The amounts of various calcilytic compounds to be administered can be determined by standard procedures taking into account factors such as the compound IC₅₀, EC₅₀, the biological half-life of the compound, the age, size and weight of the patient, and the disease or disorder associated with the patient. The importance of these and other factors to be considered are known to those of ordinary skill in the art.

Amounts administered also depend on the routes of administration and the degree of oral bioavailability. For example, for compounds with low oral bioavailability, relatively higher doses will have to be administered or the number of doses will have to be increased.

Preferably the composition is in unit dosage form. For oral application, for example, a tablet, or capsule may be administered, for nasal application, a metered aerosol dose may be administered, for transdermnal application, a topical formulation or patch may be administered and for transmucosal delivery, a buccal patch may be administered. In each case, dosing is such that the patient may administer a single dose.

Each dosage unit for oral administration contains suitably from 0.01 to 500 mg/Kg, and preferably from 0.1 to 50 mg/Kg, of a compound of Formula (I) or a pharmaceutically acceptable salt thereof, calculated as the free base. The daily dosage for parenteral, nasal, oral inhalation, transmucosal or transdermal routes contains suitably from 0.01 mg to 100 mg/Kg, of a compound of Formula(I). A topical formulation contains suitably 0.01 to 5.0% of a compound of Formula (I). The active ingredient may be administered from 1 to 6 times per day, preferably once, sufficient to exhibit the desired activity, as is readily apparent to one skilled in the art.

As used herein, “modulator” means antagonist.

As used herein, “treatment” of a disease includes, but is not limited to prevention, retardation and prophylaxis of the disease.

The compounds of the present invention preferably exhibit a ratio of β-receptor binding to calcium receptor binding (in K_(i) values) of 3 or greater, more preferably of 10 or greater, most preferably of 30 or greater.

Diseases and disorders which might be treated or prevented, based upon the affected cells, include bone and mineral-related diseases or disorders; hypoparathyroidism; those of the central nervous system such as seizures, stroke, head trauma, spinal cord injury, hypoxia-induced nerve cell damage, such as occurs in cardiac arrest or neonatal distress, epilepsy, neurodegenerative diseases such as Alzheimer's disease, Huntington's disease and Parkinson's disease, dementia, muscle tension, depression, anxiety, panic disorder, obsessive-compulsive disorder, post-traumatic stress disorder, schizophrenia, neuroleptic malignant syndrome, and Tourette's syndrome; diseases involving excess water reabsorption by the kidney, such as syndrome of inappropriate ADH secretion (SIADH), diseases involving abnormally low serum parathyroid levels, cirrhosis, congestive heart failure, and nephrosis; hypertension; preventing and/or decreasing renal toxicity from cationic antibiotics (e.g., aminoglycoside antibiotics); gut motility disorders such as diarrhea and spastic colon; GI ulcer diseases; GI diseases with excessive calcium absorption such as sarcoidosis; autoimmune diseases and organ transplant rejection; squamous cell carcinoma, and pancreatitis.

In a preferred embodiment of the present invention, the present compounds are used to increase serum parathyroid (“PTH”) levels in a pulsatile manner. Increasing serum PTH levels can be helpful in treating diseases such as hypoparathyroidism, osteosarcoma, periodontal disease, fracture, osteoarthritis, rheumatoid arthritis, Paget's disease, humoral hypercalcemia malignancy and osteoporosis. Increasing serum PTH levels can be used to treat various diseases including bone and mineral related diseases.

Various embodiments of the present invention include administering the compound to a patient to cause an increase in serum PTH having a duration up to one hour, one hour to twenty-four hours, one hour to twelve hours, one hour to six hours, one hour to five hours, one hour to four hours, two to five hours, two hours to four hours, or three hours to about six hours.

Various additional embodiments include administering the compound to a patient to cause an increase in serum PTH up to 0.5 fold, 0.5 to 5 fold, 5 fold to 10 fold, and at least 10 fold, greater than the peak serum PTH in the patient. The peak serum level is measured with respect to the patient not undergoing treatment.

Compositions of Formula (I) and their pharmaceutically acceptable salts which are active when given orally can be formulated as syrups, tablets, capsules and lozenges. A syrup formulation will generally consist of a suspension or solution of the compound or salt in a liquid carrier for example, ethanol, peanut oil. olive oil, glycerine or water with a flavoring or coloring agent. Where the composition is in the form of a tablet, any pharmaceutical carrier routinely used for preparing solid formulations may be used. Examples of such carriers include magnesium stearate, terra alba, talc, gelatin, acacia, stearic acid, starch, lactose and sucrose. Where the composition is in the form of a capsule, any routine encapsulation is suitable, for example using the aforementioned carriers in a hard gelatin capsule shell. Where the composition is in the form of a soft gelatin shell capsule any pharmaceutical carrier routinely used for preparing dispersions or suspensions may be considered, for example aqueous gums, celluloses, silicates or oils, and are incorporated in a soft gelatin capsule shell.

Typical parenteral compositions consist of a solution or suspension of a compound or salt in a sterile aqueous or non-aqueous carrier optionally containing a parenterally acceptable oil, for example polyethylene glycol, polyvinylpyrrolidone, lecithin, arachis oil or sesame oil.

Typical compositions for inhalation are in the form of a solution, suspension or emulsion that may be administered as a dry powder or in the form of an aerosol using a conventional propellant such as dichlorodifluorometbane or trichlorofluoromethane.

A typical suppository formulation comprises a compound of Formula (I) or a pharmaceutically acceptable salt thereof which is active when administered in this way, with a binding and/or lubricating agent, for example polymeric glycols, gelatins, cocoa-butter or other low melting vegetable waxes or fats or their synthetic analogs.

Typical dermal and transdermal formulations comprise a conventional aqueous or non-aqueous vehicle, for example a cream, ointment, lotion or paste or are in the form of a medicated plaster, patch or membrane.

Preferably the composition is in unit dosage form, for example a tablet, capsule or metered aerosol dose, so that the patient may administer a single dose.

No unacceptable toxological effects are expected when compounds of the present invention are administered in accordance with the present invention.

The biological activity of the compounds of Formula (I) are demonstrated by the following tests:

(I) Calcium Receptor Inhibitor Assay

Calcilytic activity was measured by determining the IC₅₀ of the test compound for blocking increases of intracellular Ca²⁺ elicited by extracellular Ca²⁺ in HEK 293 4.0-7 cells stably expressing the human calcium receptor. HEK 293 4.0-7 cells were constructed as described by Rogers et al., J. Bone Miner. Res. 10 Suppl. 1:S483, 1995 (hereby incorporated by reference herein). Intracellular Ca²⁺ increases were elicited by increasing extracellular Ca²⁺ from 1 to 1.75 mM. Intracellular Ca²⁺ was measured using fluo-3, a fluorescent calcium indicator.

The procedure was as follows:

Cells were maintained in T-150 flasks in selection media (DMEM supplemented with 10% fetal bovine serum and 200 ug/mL hygromycin B), under 5% CO₂:95% air at 37° C. and were grown up to 90% confluency. The medium was decanted and the cell monolayer was washed twice with phosphate-buffered saline (PBS) kept at 37° C. After the second wash, 6 mL of 0.02% EDTA in PBS was added and incubated for 4 minutes at 37° C. Following the incubation, cells were dispersed by gentle agitation. Cells from 2 or 3 flasks were pooled and pelleted (100×g). The cellular pellet was resuspended in 10-15 mL of SPF-PCB+ and pelleted again by centrifugation. This washing was done twice. Sulfate- and phosphate-free parathyroid cell buffer (SPF-PCB) contains 20 MM Na-Hepes, pH 7.4, 126 mM NaCl, 5 mM KCl, and 1 mM MgCl₂. SPF-PCB was made up and stored at 4° C. On the day of use, SPF-PCB was supplemented with 1 mg/mL of D-glucose and 1 mM CaCl₂ and then split into two fractions. To one fraction, bovine serum albumin (BSA; fraction V, ICN) was added at 5 mg/mL (SPF-PCB+). This buffer was used for washing, loading and maintaining the cells. The BSA-free fraction was used for diluting the cells in the cuvette for measurements of fluorescence. The pellet was resuspended in 10 mL of SPF-PCB+ containing 2.2 uM fluo-3 (Molecular Probes) and incubated at room temperature for 35 minutes. Following the incubation period, the cells were pelleted by centrifugation. The resulting pellet was washed with SPF-PCB+. After this washing, cells were resuspended in SPF-PCB+ at a density of 1-2×10⁶ cells/mL. For recording fluorescent signals, 300 uL of cell suspension were diluted in 1.2 mL of SPF buffer containing 1 mM CaCl₂ and 1 mg/mL of D-glucose. Measurements of fluorescence were performed at 37° C. with constant stirring using a spectrofluorimeter. Excitation and emission wavelengths were measured at 485 and 535 nm, respectively. To calibrate fluorescence signals, digitonin (5 mg/mL in ethanol) was added to obtain F_(max), and the apparent F_(min) was determined by adding Tris-EGTA (2.5 M Tris-Base, 0.3 M EGTA). The concentration of intracellular calcium was calculated using the following equation: Intracellular calcium=(F-F_(min)/F_(max))×Kd; where Kd=400 nM.

To determine the potential calcilytic activity of test compounds, cells were incubated with test compound (or vehicle as a control) for 90 seconds before increasing the concentration of extracellular Ca²⁺ from 1 to 2mM. Calcilytic compounds were detected by their ability to block, in a concentration-dependent manner, increases in the concentration of intracellular Ca²⁺ elicited by extracellular Ca²⁺.

In general, those compounds having lower IC₅₀ values in the Calcium Receptor Inhibitor Assay are more preferred compounds. Compounds having an IC₅₀ greater than 50 uM were considered to be inactive. Preferred compounds are those having an IC₅₀ of 10 uM or lower, more preferred compounds have an IC₅₀ of 1 uM, and most preferred compounds have an IC₅₀ of 0.1 uM or lower.

(II) Calcium Receptor Binding Assay

HEK 293 4.0-7 cells stably transfected with the Human Parathyroid Calcium Receptor(“HuPCaR”) were scaled up in T180 tissue culture flasks. Plasma membrane is obtained by polytron homogenization or glass douncing, in buffer (50 mM Tris-HCl pH 7.4, 1 mM EDTA, 3 mM MgCl₂) in the presence of a protease inhibitor cocktail containing 1 uM Leupeptin, 0.04 uM Pepstatin, and 1 mM PMSF. Aliquoted membrane was snap frozjen and stored at −80° C. ³H labeled compound was radiolabeled to a radiospecific activity of 8 l Ci/mmole and was aliquoted and stored in liquid nitroen for radiochemical stability.

A typical reaction mixture contains 2 nM ³H compound ((R,R)-N-4′-methoxy-t-3-3′-methyl-1′-ethylphenyl-1-(1-naphthyl)ethylamine), 4-10 ug membrane in homogenization buffer containing 0.1% gelatin and 10% EtOH in a reaction volume of 0.5 mL. Incubation is performed in 12×75 polyethylene tubes in an ice water bath. To each tube 25 uL of test sample in 100% EtOH is added, followed by 400 uL of cold incubation buffer, and 25 uL of 20 nM ³H-compound in 100% EtOH. The binding reaction is initiated by the addition of 50 uL of 80-200 ug/mL HEK 293 4.0-7 membrane diluted in incubation buffer, and allowed to incubate at 4° C. for 30 min. Wash buffer is 50 mM Tris-HCl containing 0.1I% PEI. Nonspecific binding is determined by the addition of 100-fold excess of unlabeled homologous ligand, and is generally 30% of total binding. The binding reaction is terminated by rapid filtration onto 1% PEI pretreated GF/C filters using a Brandel Harvestor. Filters are placed in scintillation fluid and radioactivity assessed by liquid scintillation counting.

III β-adrenergic Receptor Binding Assay

The β-Adrenergic Receptor Binding Assay is carried out as follows. Incubations are performed in polypropylene reaction tubes in a 37° C. water bath. To each tube 50 uL of test sample is added, followed by 300 uL of assay buffer (50 mM Tris-HCl, pH 7.5), and 50 uL of 20 nM [³H]-dihydroalprenolol. The binding reaction is initiated by the addition of 100 uL of 3.75 mg/mL well-washed rat cortex membranes in assay buffer, and allowed to incubate at 37° C. for 30 minutes. Non-specific binding is determined in the presence of 10 μM alprenolol. The final concentration of reactants is: 2 nM [³H]-dihydroalprenolol, and 75 mg/mL rat cortex membrane in a reaction volume of 0.5 mL.

The binding reaction is terminated by rapid filtration with ice-cold assay buffer onto GF/C filters (Brandel, Gaithersburg, Md.) which have been soaked for 15 minutes in assay buffer. The reaction is first diluted with 3 mL of cold assay buffer (4° C.), then aspirated onto the filter followed by 3×3 mL washes. Filter disks are placed in 7-mL polypropylene scintillation vials with 5 mL of ScintiSafe 50% (Fisher Scientific, Pittsburgh, Pa.), and counted overnight.

β-adrenergic activity can be reduced using appropriate functional groups and structural modifications. β-adrenergic receptor activity and binding to the β-adrenergic receptor can be measured using standard techniques. For example, see Riva et al., Mol. Pharmacol, 36:201-210, 1989.

In one embodiment of the present invention the calcilytic compounds have a K_(i)≧0.1 uM, at the β-adrenergic receptor as measured using the β-Adrenergic Receptor Binding Assay described above. In other embodiments, using the β-Adrenergic Receptor Assay calcilytic compounds have a K_(i)≧1.0 uM, and K_(i)≧10.0 uM.

The following examples are illustrative, but not limiting of the embodiments of the present invention.
